Abstract: PROBLEM TO BE SOLVED: To effectively utilize a rate of other virtual channel by judging accurately a time-out time at a high speed so as to detect earlier a non-use state of a virtual channel. SOLUTION: An FIFO memory 10 receives input information 101 denoting line number information of a virtual channel in a received RM cell and a clock 102 to activate the FIFO memory 10 and provides an output of input information 101 having a time-out time denoting a time lag of N fold of a period of the clock 102 as output information 103 of the FIFO. The device is provided with an addition processing section and a subtraction processing section which count how many information sets of each virtual channel are stored in the FIFO memory 10 between a current time and a time before the time-out time by using the FIFO memory 10 with a lag of the time-out time and the results of the count are stored in a RAM 20.  Since the RAM memory 20 observes the time-out and the addition processing section and the subtraction processing section have only to conduct +1 increment and -1 decrement respectively, high speed processing is attained.
